Interesting. Deserts around the world have similar patterned landscapes:
A new study published in Nature has found that Namibian Fairy Circles are the product of not one, but two ecological forces. By combining field observations and computer models, researchers from Princeton University, the University of Strathclyde in Glasgow, and several other institutions, have shown that the interaction between both termites and self-organizing plants (i.e. plants that either clump themselves together or disperse according to the availability of resources) is sufficient to explain this enigmatic landscape feature. Importantly, this new theory could be used to solve similar mysteries around the world.
